CarComplaints.com Notes: The only area of real concern for 2010 Mazda CX-9 owners is the brake booster.
In 2014, Mazda extended the warranty on the 2007-2013 CX-9 brake booster to 7 years / 90,000 miles. However this extended warranty has expired, so buyer beware.
This Mazda CX-9 brake booster failure isn't terrible in terms of repair cost — it "only" costs $550 average to fix. However it is a safety issue when the brake booster fails as it increases stopping distance. Owners have reported having to stomp on the brake pedal, & crashes/injuries have been reported due to this CX-9 brake booster defect.
The steering slips on a hard left turn. The car will start the turn normally, then if the turn is sharp enough the is a small slip. it feels like the steering then hits a stop and the steering holds through the rest of the turn. When you straighten up again you can feel a looseness in the steering for a moment then everything is normal again. It feel like there is a bolt loose in the steering, and it slips until it hits the nut and then is normal. It only happens when turning left, no problems turning right. I had my mechanic look at it and he couldn't find anything wrong. Any ideas what else to look at?
